A Novel Broadband Class E Power Amplifier with Inductance Feedback

摘要：

This paper proposed a new broadband parallel-circuit class E power amplifier(PA) design with feedback inductance. The effect of the feedback inductance on the drain efficiency is studied with an analytical method by using Fourier transformation. Analytical results show that drain efficiency greater than 90％ is achieved over a frequency bandwidth of 64％ by introducing inductance feedback. Simulation based on a SiC MESFET CRF24060 is presented to verify the validity of our method, which shows a drain efficiency greater than 70％ over a bandwidth of 62％.
